GRAIN-CHUTE.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed August 24, 1912. Serial No. 716,862.

To all whom it may concern Be it known that I, CLYDE L. NEiswANenR, acitizen of the United States, residing at Bladen, in the county ofebster and State ofNebraska, have invented a new and useful Grain-Chute;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as w ll enable others skilled in theart to which it appei'tains to make and use the same. I

This invention relates to a new and useful grain chute adapted for usein connection with grain bins of granaries.

As one of the objects of this invention, a vertical sliding door or gateis provided, having connections with a pivoted section of the chute orspout, whereby as said section is lowered in position, the door isopened, and when the said section is raised out of position, the door isautomatically closed.

The invention comprises further features and combinations of parts, ashereinafter set forth, shown in the drawings and c la1med.

In the drawings, Figure 1 is a view showing the application of theimproved chute or spout, showing the door open and the sectional chuteswung downwardly. Fig. 2 is a sectional view on line 2-2 of Fig. 1. Fig.3 is a view similar to Fig. 2, showing the door closed and the sectionof the chute raised. Fig. 4 is a detail view of the connections betweenthe door and the movable section of Fig. 6

the chute. Fig. 5 is a detail view. is a detail view of the rod 33.

Referring more particularly to the dra W- ings, 1 designates a portionof a grain bin, in which, by the screws 2, the chute or spout 3 isfastened. The chute or spout comprises the two parts 4 and 5, which aretroughshaped, one secured within the other by the bolts 6 including nuts7. Secured in the trough-shaped part 4 is an inclined portion or plate8. Mounted in guides 9 of the part 4 is a door 10, upon the rear face ofwhich a strap 11 is secured. Fastened by any suitable means 11 to theopposite sides of the 4, and extending transversely thereof, is a bar12, to which a lever 13 is pivoted at 14. The door 10 closes an opening15. Connecting one end 17 of the lever is a rod 18, the lower end ofwhich is connected to the strap of the door. The other end 19 of thelever has pivoted to it a rod 20, the end 21 of which is pivoted at 22to the lever 23. This part lever 23 is pivoted at 24 to one side of thepart 4 of the chute or spout. The end 25 of the lever 23 is constructedwith a slot 26, which, when the door 10 is closed, registers with theelongated portion 27 of the slot 28, which is formed in one side of thepart 4 of the chute or spout. The upper end of the slot 28 terminates ina curved cam .slot 29.

Hinged at 30 to the part 4 is a pivoted chute or spout 31, which isprovided with extensions 32, one of which has pivoted to it a rod 33.The upper end of the rod 33 terminates in a lateral portion 34, whichmoves in the elongated portion 27 of the slot 28, and also in the curvedcam portion thereof. hen the hinged chute or spout is in a raisedposition, the lateral portion 34 of the rod is in the lower end of theelongated portion 27 of the slot 28, but when the hinged chute or spoutis being lowered, the lateral portion 34 moves upwardly in the elongatedportion 27 of the slot 28 and engages the slot 26 of the lever 23. Asthe hinged chute or spout further lowers, the lever 23 is rocked uponits pivot, which, in turn, will rock the lever 13 through the medium ofthe rod con nection, and when the lever 13 is rocked, the door 10 willbe raised, thereby allowing the grain to pass through the door openinginto the hinged chute or spout. As the lever 23 is rocked in thismanner, the lateral portion 34 of the rod 33 moves through the camcurved slot 29. When the hinged chute or spout is raised, the reverse ofthese operations is accomplished, thereby closing the door 10. When thehinged chute or spout is fully raised, the same is held in such positionby the slotted tongue 37 hinged at 38 to the part 4 engaging the staple39, which receives the usual form of padlock 40.

From the foregoing it will be noted that there has been devised asimple, novel and efficient construction, and one which has been founddesirable and practical.

The invention having been set forth, what is claimed as new and usefulis 1. In combination, a chute having an opening, a door therefor, aspout hinged to the chute and provided with an extension, a rodconnected to the extension and provided with a lateral portion, thechute having an elongated slot terminating at its upper portion in acurved cam slot, said slots receiving the lateral portion of the rod,and means actuated by said lateral portion for opening or closing thedoor when the hinged spout is raised or lowered.

2. In combination, a chute having an opening, a door therefor, a spouthinged to the chute and provided with an extension, a rod connected tothe extension and provided with a lateral portion, the chute having anelongated slot terminating at its upper/portion in a curved cam slot,said slots receiving the lateral portion of the rod, a lever pivoted inthe chute and constructed with an angular slot at one end adapted toreceive the lateral portion of the rod when the hinged spout is lowered,and means connected between the lever and the door whereby the door isopened or closed as the spout is lowered or raised.

8. In combination, a chute having an opening and provided withia hingedspout, a door for said opening, guides for the door, the chute having anelongated slot terminating at its upper portion in a curved cam portion,and connections between the hinged spout and the door, whereby as thespout is raised or lowered, the door will be closed or opened, theconnections including a rod having a portion operable in the slot, saidconnections including a pivoted member to be actuated by said portion ofthe rod.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
